Abstract (en)
[origin: WO2009036124A2] A speaker system (100) that includes a printed circuit board (PCB) (101) and a speaker assembly (102, 103, 104, 105). The speaker assembly (102, 103, 104, 105) is embedded in the PCB (101). The speaker assembly (102, 103, 104, 105) may include a coil (102), a magnet (103), and a diaphragm (105). The coil (102) is embedded in a material of the PCB (101). The magnet (103) is located within the PCB (101) and attached to the diaphragm (105). The coil (102) is useable as a T-coil for hearing aid compatibility. The speaker system (100) may be included in any device (400) such as a mobile phone, a personal digital assistant (PDA), a computer, an electronic game device, an electronic audio device, or an electronic video device.
